Feng Shui is the belief that items and furniture can be arranged in your house to
increase the flow of life energy. This is thought to bring good health and good
luck. Animal Crossing has its own form of Feng Shui. In Animal Crossing you place
Yellow furniture and items on the West (left) side, red items and furniture to the
East (right) side and green items and furniture to the South (bottom). This is said
to give higher scores when it comes to the Happy Room Academy (HRA).

Additionally there are "Lucky" items. These items can be placed anywhere. These
items add 7,777 points to your HRA score. Although multiple copies of the same item
are not cumulative. Meaning that you will only get 7,777 points even if you have
two Arwings.
